Fixes #25342.
Still not sure on the exact user agent to set (should it include
`node`?).
After this PR, here's the state of running some `create-*` packages
(just ones I could think of off the top of my head):
| package | prints/runs/suggests deno install | notes |
| ---------------- | ------------- | ------ |
| `create-next-app` | ❌ | falls back to npm, needs a PR
([code](c32e280209/packages/create-next-app/helpers/get-pkg-manager.ts (L3)))
| `sv create` | ❌ | uses `package-manager-detector`, needs a PR
([code](https://github.com/antfu-collective/package-manager-detector/tree/main))
| `create-qwik` | ✅ | runs `deno install` but suggests `deno start`
which doesn't work (should be `deno task start` or `deno run start`)
| `create-astro` | ✅ | runs `deno install` but suggests `npm run dev`
later in output, probably needs a PR
| `nuxi init` | ❌ | deno not an option in dialog, needs a PR
([code](f04e2e8944/src/commands/init.ts (L96-L102)))
| `create-react-app` | ❌ | uses npm
| `ng new` (`@angular/cli`) | ❌ | uses npm
| `create-vite` | ✅ | suggests working deno commands 🎉
| `create-solid` | ❌ | suggests npm commands, needs PR
It's possible that fixing `package-manager-detector` or other packages
might make some of these just work, but haven't looked too carefully at
each
This PR addresses issue #25600
Changes:
Updated `fn has_hmr` to check `serve` subcommand and return its hmr
value if found, in order to run the worker in serve mode with
hmr_runner. Thus the hmr event can be dispatched upon changes on the
file served.
Fixes https://github.com/denoland/deno/issues/26509.
Ended up being a `deno_graph` bug causing the error to surface. This PR
updates `deno_graph` to pick up the fix and reverts the temporary
workaround that skipped JSON exports.
Fixes #26498.
This was a sort of intentional decision originally, as I wanted to avoid
caching extra files that may not be needed. It seems like that behavior
is unintuitive, so I propose we cache all of the exports of listed jsr
packages when you run a bare `deno install`.
This commit makes sure that `deno add`, `deno install` and `deno remove`
update the lockfile if only `package.json` file is present.
Fixes https://github.com/denoland/deno/issues/26270
1. Respects the formatting of the file (ex. keeps four space indents or
tabs).
2. Handles editing of comments.
3. Handles trailing commas.
4. Code is easier to maintain.
This PR fixes the issue where mapped specifiers in a workspace member
would never be found. Only mapped paths from the workspace root would
resolve.
This was caused by always passing the workspace root url to the import
map resolver instead of the workspace member one.

I don't have a reliable reproduction for it, but it makes it
painful to use the Jupyter kernel with semi-frequent random panics.
The completions don't always work correctly anyway, so I think
it's better to just not panic here for the time being.
Fixes https://github.com/denoland/deno/issues/26340
Fixes #26085.
Adds a basic retry utility with some defaults, starts off with a 100ms
wait, then 250ms, then 500ms
I've applied the retry in the http client, reusing an existing function,
so this also applies to retrying downloads of deno binaries in `upgrade`
and `compile`. I can make a separate function that doesn't retry so this
doesn't affect `upgrade` and `compile`, but it seemed desirable to have
retries there too, so I left it in.
Fixes https://github.com/denoland/deno/issues/26119.
Originally I wanted to put them in package.json if there's no deno.json,
but on second thought it makes more sense to just create a deno.json
When using the `--unstable-detect-cjs` flag or adding `"unstable":
["detect-cjs"]` to a deno.json, it will make a JS file CJS if the
closest package.json contains `"type": "commonjs"` and the file is not
an ESM module (no TLA, no `import.meta`, no `import`/`export`).
This replaces `--allow-net` for import permissions and makes the
security sandbox stricter by also checking permissions for statically
analyzable imports.
By default, this has a value of
`--allow-import=deno.land:443,jsr.io:443,esm.sh:443,raw.githubusercontent.com:443,gist.githubusercontent.com:443`,
but that can be overridden by providing a different set of hosts.
Additionally, when no value is provided, import permissions are inferred
from the CLI arguments so the following works because
`fresh.deno.dev:443` will be added to the list of allowed imports:
```ts
deno run -A -r https://fresh.deno.dev
```

Fixes #25813.
I initially tried doing this in `deno_semver`, where it's a cleaner
change, but that caused breakage in deno in places where we don't expect
a tag (see https://github.com/denoland/deno/issues/25857).
This does not fix wildcard requirements failing to choose pre-release
versions. That's a little more involved and I'll do a separate PR.
`deno fmt --check` was broken for CSS, YAML and HTML files.
Before this PR, formatting any of these file types would return a
string, even though the contract in `cli/tools/fmt.rs` is to only return a
string if the formatting changed. This causes wrong flagging of these files
as being badly formatted even though diffs showed nothing (because
they were in fact formatted properly).
Closes https://github.com/denoland/deno/issues/25840
Fixes #25802
markup_fmt plugin supports some HTML-like formats like Angular, Jinja,
Twig, Nunjucks or Vento, that are not supported by `deno fmt`. This PR
adds support for the extensions `njk` (Nunjucks) and `vto` (Vento).
Angular doesn't have a custom extension (it uses `html` afaik) and Jinja
and Twig are template engines written in Python and PHP respectively so
it doesn't make sense to be supported by Deno.
This commits stabilizes CSS, HTML and YAML formatters
in `deno fmt`.
It is no longer required to use either of these flags:
- `--unstable-css`
- `--unstable-html`
- `--unstable-yaml`
Or these `unstable` options in the config file:
- `fmt-css`
- `fmt-html`
- `html-yaml`
This commit lets `deno test --doc` command actually evaluate code snippets in
JSDoc and markdown files.
## How it works
1. Extract code snippets from JSDoc or code fences
2. Convert them into pseudo files by wrapping them in `Deno.test(...)`
3. Register the pseudo files as in-memory files
4. Run type-check and evaluation
We apply some magic at the step 2 - let's say we have the following file named
`mod.ts` as an input:
````ts
/**
* ```ts
* import { assertEquals } from "jsr:@std/assert/equals";
*
* assertEquals(add(1, 2), 3);
* ```
*/
export function add(a: number, b: number) {
return a + b;
}
````
This is virtually transformed into:
```ts
import { assertEquals } from "jsr:@std/assert/equals";
import { add } from "files:///path/to/mod.ts";
Deno.test("mod.ts$2-7.ts", async () => {
assertEquals(add(1, 2), 3);
});
```
Note that a new import statement is inserted here to make `add` function
available. In a nutshell, all items exported from `mod.ts` become available in
the generated pseudo file with this automatic import insertion.
The intention behind this design is that, from library user's standpoint, it
should be very obvious that this `add` function is what this example code is
attached to. Also, if there is an explicit import statement like
`import { add } from "./mod.ts"`, this import path `./mod.ts` is not helpful for
doc readers because they will need to import it in a different way.
The automatic import insertion has some edge cases, in particular where there is
a local variable in a snippet with the same name as one of the exported items.
This case is addressed by employing swc's scope analysis (see test cases for
more details).
## "type-checking only" mode stays around
This change will likely impact a lot of existing doc tests in the ecosystem
because some doc tests rely on the fact that they are not evaluated - some cause
side effects if executed, some throw errors at runtime although they do pass the
type check, etc. To help those tests gradually transition to the ones runnable
with the new `deno test --doc`, we will keep providing the ability to run
type-checking only via `deno check --doc`. Additionally there is a `--doc-only`
option added to the `check` subcommand too, which is useful when you want to
type-check on code snippets in markdown files, as normal `deno check` command
doesn't accept markdown.

**Code Changes**
- Updated malva version to the latest in cli/Cargo.toml.
- Updated LanguageOptions to match new Malva config.
- Added test case same as the issue to assure changes success.
Closes https://github.com/denoland/deno/issues/25321
Ended up being a larger refactoring, since we're now juggling
(potentially) two config files in the same `add`, instead of choosing
one. I don't love the shape of the code, but I think it's good enough
Some smaller side improvements:
- `deno remove` supports `jsonc`
- `deno install --dev` will be a really simple change
- if `deno remove` removes the last import/dependency in the
`imports`/`dependencies`/`devDependencies` field, it removes the field
instead of leaving an empty object
The map field has been empty for years now and we don't want the emit
file to be exposed so it allows us to iterate on making the cache
faster. Additionally, it's racy/unreliable to rely on this information.
Instead, people should emit the TS files themselves using tools like
deno_emit, typescript, esbuild, etc.
Closes https://github.com/denoland/deno/issues/17703
These now works:
```
$ deno add @std/dotenv/load
$ deno add npm:preact/hooks
```
Previously we were erroring out, because this is a "package reference"
including
a subpath.

Unlike in dprint, `single_quote` option is shared between all

Fixes #24607.
This PR makes the logic that caches top level dependencies (things
present in import map) smarter, so we handle JSR dependencies without
root exports.
- rewrite flag help
- use gray for indentation
- reorganize permission flags and split them up
- make help subcommand act like help flag
- `deno run` outputs list of tasks
- Fixes #25120
error handling for `deno run` in case of no config file being found
needs to be improved
